以美化形式从MongoDB集合中获取所有文档
要获取文档，请find()在MongoDB中使用。这样，可以格式化结果文档pretty()。
让我们创建一个包含文档的集合-
> db.demo306.insertOne({"Name":"Robert","Age":21});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e4ea7c6f8647eb59e562038")
}
> db.demo306.insertOne({"Name":"David","Age":23});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e4ea7cdf8647eb59e562039")
}
> db.demo306.insertOne({"Name":"Mike","Age":25});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e4ea7d4f8647eb59e56203a")
}
> db.demo306.insertOne({"Name":"Carol","Age":26});
{
"acknowledged" : true,
"insertedId" : ObjectId("5e4ea7dcf8647eb59e56203b")
}在find()方法的帮助下显示集合中的所有文档-
> db.demo306.find().pretty();
这将产生以下输出-
{
"_id" : ObjectId("5e4ea7c6f8647eb59e562038"),
"Name" : "Robert",
"Age" : 21
}
{
"_id" : ObjectId("5e4ea7cdf8647eb59e562039"),
"Name" : "David",
"Age" : 23
}
{
"_id" : ObjectId("5e4ea7d4f8647eb59e56203a"),
"Name" : "Mike",
"Age" : 25
}
{
"_id" : ObjectId("5e4ea7dcf8647eb59e56203b"),
"Name" : "Carol",
"Age" : 26
}
